Visual Hypothesis Testing with Confidence Intervals
A simple visual method of comparing means given normal %~. confidence intervals is proposed. Monte Carlo simulations were used to derive a visual rule of thumb that can be used to test the null hypothesis of equal means, given the confidence intervals of the means, and the sample sizes (or degrees of freedom). The type-1 error rate of the test is approximately .05. The rule involves accepting t...
متن کاملA practical guide for understanding confidence intervals and P values.
The 95 percent confidence interval about the mean demarcates the range of values in which the mean would fall if many samples from the universal parent population were taken. In other words, if the same observation, experiment, or trial were done over and over with a different sample of subjects, but with the same characteristics as the original sample, 95 percent of the means from those repeat...
متن کاملConfidence intervals for change in automated visual fields.
Three successive fields of 136 eyes (86 patients) were extracted from our data base containing over 3000 visual fields performed on the Humphrey visual field analyser with program 30-2. Series of fields in which the second field was depressed relative to the first were selected for analysis to determine how much change between the first two fields was required to predict a downward trend as con...
متن کاملHow confidence intervals become confusion intervals
BACKGROUND Controversies are common in medicine. Some arise when the conclusions of research publications directly contradict each other, creating uncertainty for frontline clinicians. DISCUSSION In this paper, we review how researchers can look at very similar data yet have completely different conclusions based purely on an over-reliance of statistical significance and an unclear understand...
متن کاملProbabilistic Intervals of Confidence
Abstract: High accuracy should not be the only goal of classification: information concerning probable alternatives diagnoses, probability of these diagnoses, evaluation of confidence in classification, are also important. Neural models are used just to obtain the winner class but do not provide any justification for their recommendations – they work as black boxes. A method which determine con...
